|---|---|---|---|---|---|
| CVE-2020-28016 | 1 Exim | 1 Exim | 2024-02-28 | 7.2 HIGH | 7.8 HIGH |
| Exim 4 before 4.94.2 allows an off-by-two Out-of-bounds Write because "-F ''" is mishandled by parse_fix_phrase. | |||||
| CVE-2020-28014 | 1 Exim | 1 Exim | 2024-02-28 | 5.6 MEDIUM | 6.1 MEDIUM |
| Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. The -oP option is available to the exim user, and allows a denial of service because root-owned files can be overwritten. | |||||
| CVE-2020-28011 | 1 Exim | 1 Exim | 2024-02-28 | 7.2 HIGH | 7.8 HIGH |
| Exim 4 before 4.94.2 allows Heap-based Buffer Overflow in queue_run via two sender options: -R and -S. This may cause privilege escalation from exim to root. | |||||
| CVE-2020-28026 | 1 Exim | 1 Exim | 2024-02-28 | 9.3 HIGH | 9.8 CRITICAL |
| Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters, relevant in non-default configurations that enable Delivery Status Notification (DSN). Certain uses of ORCPT= can place a newline into a spool header file, and indirectly allow unauthenticated remote attackers to execute arbitrary commands as root. | |||||
| CVE-2020-28010 | 1 Exim | 1 Exim | 2024-02-28 | 7.2 HIGH | 7.8 HIGH |
| Exim 4 before 4.94.2 allows Out-of-bounds Write because the main function, while setuid root, copies the current working directory pathname into a buffer that is too small (on some common platforms). | |||||
| CVE-2020-28024 | 1 Exim | 1 Exim | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| Exim 4 before 4.94.2 allows Buffer Underwrite that may result in unauthenticated remote attackers executing arbitrary commands, because smtp_ungetc was only intended to push back characters, but can actually push back non-character error codes such as EOF. | |||||
| CVE-2021-27216 | 1 Exim | 1 Exim | 2024-02-28 | 6.3 MEDIUM | 6.3 MEDIUM |
| Exim 4 before 4.94.2 has Execution with Unnecessary Privileges. By leveraging a delete_pid_file race condition, a local user can delete arbitrary files as root. This involves the -oP and -oPX options. | |||||
| CVE-2020-28021 | 1 Exim | 1 Exim | 2024-02-28 | 9.0 HIGH | 8.8 HIGH |
| Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters. An authenticated remote SMTP client can insert newline characters into a spool file (which indirectly leads to remote code execution as root) via AUTH= in a MAIL FROM command. | |||||
| CVE-2020-28017 | 1 Exim | 1 Exim | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow in receive_add_recipient via an e-mail message with fifty million recipients. NOTE: remote exploitation may be difficult because of resource consumption. | |||||
| CVE-2020-28015 | 1 Exim | 1 Exim | 2024-02-28 | 7.2 HIGH | 7.8 HIGH |
| Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters. Local users can alter the behavior of root processes because a recipient address can have a newline character. | |||||
| CVE-2020-28013 | 1 Exim | 1 Exim | 2024-02-28 | 7.2 HIGH | 7.8 HIGH |
| Exim 4 before 4.94.2 allows Heap-based Buffer Overflow because it mishandles "-F '.('" on the command line, and thus may allow privilege escalation from any user to root. This occurs because of the interpretation of negative sizes in strncpy. | |||||
| CVE-2020-12783 | 4 Canonical, Debian, Exim and 1 more | 4 Ubuntu Linux, Debian Linux, Exim and 1 more | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
| Exim through 4.93 has an out-of-bounds read in the SPA authenticator that could result in SPA/NTLM authentication bypass in auths/spa.c and auths/auth-spa.c. | |||||
| CVE-2020-8015 | 2 Exim, Opensuse | 2 Exim, Opensuse | 2024-02-28 | 7.2 HIGH | 7.8 HIGH |
| A UNIX Symbolic Link (Symlink) Following vulnerability in the packaging of exim in openSUSE Factory allows local attackers to escalate from user mail to root. This issue affects: openSUSE Factory exim versions prior to 4.93.0.4-3.1. | |||||
| CVE-2019-10149 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2024-02-28 | 10.0 HIGH | 9.8 CRITICAL |
| A flaw was found in Exim versions 4.87 to 4.91 (inclusive). Improper validation of recipient address in deliver_message() function in /src/deliver.c may lead to remote command execution. | |||||
| CVE-2019-13917 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-02-28 | 10.0 HIGH | 9.8 CRITICAL |
| Exim 4.85 through 4.92 (fixed in 4.92.1) allows remote code execution as root in some unusual configurations that use the ${sort } expansion for items that can be controlled by an attacker (e.g., $local_part or $domain). | |||||
| CVE-2019-15846 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-02-28 | 10.0 HIGH | 9.8 CRITICAL |
| Exim before 4.92.2 allows remote attackers to execute arbitrary code as root via a trailing backslash. | |||||
| CVE-2017-1000369 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-02-28 | 2.1 LOW | 4.0 MEDIUM |
| Exim supports the use of multiple "-p" command line arguments which are malloc()'ed and never free()'ed, used in conjunction with other issues allows attackers to cause arbitrary code execution. This affects exim version 4.89 and earlier. Please note that at this time upstream has released a patch (commit 65e061b76867a9ea7aeeb535341b790b90ae6c21), but it is not known if a new point release is available that addresses this issue at this time. | |||||
| CVE-2017-16943 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via vectors involving BDAT commands. | |||||
| CVE-2017-16944 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
| The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to cause a denial of service (infinite loop and stack exhaustion) via vectors involving BDAT commands and an improper check for a '.' character signifying the end of the content, related to the bdat_getc function. | |||||
| CVE-2016-9963 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2024-02-28 | 2.6 LOW | 5.9 MEDIUM |
| Exim before 4.87.1 might allow remote attackers to obtain the private DKIM signing key via vectors related to log files and bounce messages. | |||||
